johtavuusanturit

Johtavuusanturit, known in English as conductivity sensors, are devices used to measure the electrical conductivity of a solution. Electrical conductivity is a measure of a solution's ability to conduct electricity, which is directly related to the concentration of ions present. Higher ion concentrations lead to higher conductivity.

These sensors typically consist of two or more electrodes, often made of inert materials like platinum or stainless steel, immersed in the liquid being tested. A voltage is applied across the electrodes, and the resulting current flow is measured. This current is proportional to the conductivity of the solution. The sensor then converts this current measurement into a conductivity value, usually expressed in units of Siemens per meter (S/m) or millisiemens per centimeter (mS/cm).

Johtavuusanturit are widely used in various applications. In environmental monitoring, they help assess water quality by detecting dissolved salts and pollutants. In industrial processes, they are used for controlling the concentration of solutions, monitoring wastewater treatment, and ensuring the purity of process water. In agriculture, they can be used to measure soil salinity. The design and materials of the sensor are chosen based on the specific application, considering factors such as the expected conductivity range, temperature, and the presence of corrosive substances. Regular calibration is essential to ensure accurate readings.
